Walmart To Use Drones In Stores To Provide Better Customer Service

You walk into your local Walmart. There may be someone to greet you at the door, yet as you make your way down the aisle, you realize you need help. Within moments a drone flies down from above and hovers in front of you, then leads you to the item you're trying to find. Is this real, or is this science fiction? Walmart has filed a patent for drones to help shoppers in its stores. The way it works is simple.
